How long to get a quote?
We aim to quote all prototype projects within 24 hours. All rapid tooling projects within 24 hours. All injection molding, production and export tooling within 3 days. There are sometimes processes and materials which HLH does not offer in house; these could add time to the quotation and will be highlighted as and when.
How do you manage quality?
Stage One: full DFM at time of quotation by highly experienced engineers. They will highlight any problem areas or make suggestions for changes. Stage Two: incoming inspection of materials with our own PIM Spectrometer Stage Three: Full QC inspection and report before shipping
What are HLH’s shipping terms?
All projects are DDU unless otherwise stated. This means the quote includes all freight and charges to a port of your choice. Any and all import and other taxes in your country are your own responsibility. If you require different shipping terms these can be negotiated on a case by case basis.
What tolerances can you achieve?
HLH generally work to ISO 2768-1 (F for machined metal, M for machined plastic, C for vacuum casting). We can sometime hit tighter tolerances, but this depends on the part geometry and material. If you require tighter tolerances than the ISO standard stated above these must be stated and negotiated at the time of quotation.
What type of files do you accept for quoting?
As far as possible we prefer a step or iges file for quoting along with a 2D engineering drawing with key dimensions and tolerances detailed. For 3D printing an .obj or .stl is needed. We can quote some projects from a 2D drawing only but this is generally more time consuming.
